Mitsubishi APMT1135PDER-M2 VP15TF Carbide Milling Insert: Comprehensive Technical Guide
On this page
What is the Mitsubishi APMT1135PDER-M2 VP15TF insert?
The APMT1135PDER-M2 is a Mitsubishi Materials carbide milling insert — the 11-size, 35° rhombic double-sided shoulder-milling geometry with four cutting edges per side — in the VP15TF coated grade, Mitsubishi's general-purpose grade for steel milling. This record covers four factory boxes of ten (forty inserts), each in the yellow DIAEDGE Mitsubishi Materials case with its white type label: APMT1135PDER-M2 VP15TF, barcode, QU8849Z1JM213, MADE IN JAPAN. The clear lids carry the bilingual cobalt safety warning (California Prop 65), the holographic anti-counterfeit seal sits under the lid band, and through the transparent tops the gold-coated inserts sit in their moulded pockets. New in original packaging per the record; they passed through the Koeed warehouse on 16 October 2025 (about 0.5 kg), and the six photos below show them as received.

Why this type and grade
APMT1135 is the workhorse shoulder-milling insert: the 35° rhombic shape gives a strong edge for square-shoulder cuts while the double-sided layout gives eight usable corners per insert, and the -M2 chipbreaker suits the medium duty range most jobbing shops live in. VP15TF is Mitsubishi's long-running steel-milling grade — a gold PVD-coated carbide balanced for Carbon through alloy steels across wet and dry cutting — which is why it remains one of the most reordered types in the range. When matching a replacement, the whole string matters: APMT1135PDER-M2 fixes the geometry and seat, VP15TF fixes the grade; the DIAEDGE case, the QU8849Z1JM213 box code and the MADE IN JAPAN label in the photos confirm these are factory originals, not regrinds or copies.
